Over the last 15 years there has been a paradigm shift in North America from hydrocarbon production from conventional, permeable reservoirs to ultra-low permeability, unconventional reservoirs. The exploitation of unconventional resources is made possible by injection of large volumes (millions of litres) of fluid at high pressures to hydraulically create a permeable fracture network in the reservoir. The process of hydraulically fracturing in some areas result in anomalous induced seismicity (AIS), and the fluids used may damage the reservoir and are viewed by some as potential contaminants. The potential for AIS and real or perceived problems associated with the large volume of fluid utilised are the most important issues currently facing sustainable development of unconventional hydrocarbon resources. Our research will contribute to: 1) prevention and/or mitigation of AIS due to hydraulic fracturing; 2) understanding fluid rock interactions to minimize reservoir and fluid damage; and 3) better characterisation of reservoirs to optimise exploration and production.

在过去的15年中，北美从碳氢化合物的产量从常规的，可渗透的储层转变为非常低的渗透性，非常规的储层。通过在高压下注入大量（数百万升）的液体以在水库中建立可渗透的断裂网络，从而使非常规资源的剥削成为可能。在某些区域的水力压裂过程会导致异常诱导的地震性（AIS）和所使用的流体可能损​​坏储层，并被某些人视为潜在污染物。与使用大量流体相关的AIS以及实际或感知的问题的潜力是目前面临非常规碳氢化合物资源的可持续发展的最重要问题。我们的研究将有助于：1）由于水力压裂而导致的预防和/或缓解AIS； 2）了解流体岩石相互作用以最大程度地减少储层和流体损害； 3）更好地表征储层以优化探索和生产。
